OBJECTIVE: To assess the rates of atypical small acinar proliferation (ASAP) and high-grade prostatic intraepithelial neoplasia (HGPIN) detected in prostate biopsy in China and the risk of PCa found in subsequent repeat biopsy.
METHODS: A total of 2,456 patients underwent TRUS-guided prostate biopsy with the samples of ASAP and/or HGPIN tissues in our hospital at least twice between July 2014 and June 2019. We analyzed the findings of digital rectal examination, prostate volumes, PSA levels, and the results of prostate biopsies.
RESULTS: Initial prostate biopsies revealed 737 cases of PCa (30.0%), 215 cases of ASAP (8.8%), 98 cases of HGPIN (4.0%), and 18 cases of ASAP+HGPIN (0.7%). Totally, 313 of the patients met the inclusion criteria and included in this study. Of the 215 cases of ASAP confirmed in the first biopsy, 72 and 25 were diagnosed with PCa in the second and third biopsies, respectively, 83 with Gleason score (GS) 6, 14 with GS7, 57 with T1c and 40 with T2a tumors. Of the 98 cases of HGPIN confirmed in the first biopsy, 1 was diagnosed with PCa in the second and another 1 in the third biopsy, both with GS6 and T1c tumors. Of the 18 cases of ASAP+HGPIN confirmed in the first biopsy, 7 and 3 were diagnosed with PCa in the second and third biopsies, respectively, 7 with GS6, 3 with GS7, 6 with T1c and 4 with T2a tumors.
CONCLUSIONS: ASAP is a significant risk factor for PCa and repeat prostate biopsy should be performed for patients diagnosed with ASAP in the first biopsy. Whether repeat biopsy is necessary for those diagnosed with HGPIN depends on other related clinical parameters./.
